LOADING-MACHINE.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed August 12, 1918. Serial No. 249,392.

To all whom it may concern:

Be it known that I, CHARLES L. BLEWETT, a citizen of the United States, and a resident of Kingsley, in the county of Plymouth and State of Iowa, have invented certain new and useful Improvements in Loading- Machines, of which the following is a specification.

The invention aims, primarily, to provide an improved loading machine embodying certain novel features particularly adapting it for loading manure.

Another object of the invention is the production of a manure-loading device which may be operated by oneattendant.

Still a further object is the production of a manure-loader having an automatically controlled dispensing carrier.

Furthermore, the invention contemplates an improved manure-loading device simple and comparatively inexpensive in construction, yet durable and thoroughly efficient in operation.

With these and other objects in view, the invention, consisting in the construction, combination and novel arrangement of parts, will be fully understood from the following description, reference being had to the accompanying drawings which form a part of this application and in which like characters of reference indicate corresponding parts throughout the several views, of which,-

Figure 1 is a side elevation of a device constructed in accordance with the invention, parts being cut away;

Fig. 2 is a plan of the same;

Fig. 3 is a rear elevation of scoop being omitted; and

Fig. 4 is an enlarged side elevation of the same, the

the scoop.

Although I have illustrated and hereinafter described the preferred embodiment of the invention, I would not be understood as being limited to the specific structure chosen for illustration, for various alterations and modifications may be made in the details of construction and arrangement of parts, without departing from the spirit and scope of the invention as defined in the appended claims.

Referring, now to the illustrations, the device includes an arched frame, which may consist of two base side members 5, supporting uprights 6, interconnected at their tween the tines. plate, 12, is disposed a distance in the rear of the pointsjof the tines, and between the tines is formed with V-shaped notches to upper ends by a cross member, 7. Diagonal braces, 8, secured to the uprights and base members, hold the former against forward or rearward movements.

In use the above-described frame is placed adjacent the manure or other material to be moved; and. wagon, 9. or other conveyance backed'under the frame to receive the mater al. A scoop 1s provlded, and means for drawing the scoop toward the frame, to

provide cutting edges, 13, inclined at an angle to the direction of travel, to facilitate entrance of the scoop into the material as the scoop moves forwardly. The upwardly.- turned rear ends of the tines are connected by a cross member, 15; and the said ends of the outside tines are secured to theintermediate portions thereof by braces, 16, which may be extended rearwardly to afford handles, 17. To the lower end portions of the said braces is pivotally secured a bail, 18, having journaled at its center a pulley,19.

The frame base members, 5, extend rearwardly a distance from the uprights, and to the said extended ends are pivoted the arms of an arched boom, 20, to the center of the underside of the web of which is secured a bracket, 21, carrying upper and lower .pulleys, 22 and 23, respectively, between which passes a tackle, 24, passed around the scoop pulley, 19, and having its end secured to the lower end of the bracket, 21. From the boom the tackle passes around a direction pulley, 25, hung from the center of the top frame member, 7 then around upper and lower direction pulleys,. 26, and 27, on" one of the uprights. f 7

To 'the end, 28,'of the tackle maybe hitched draft] animals or other suitable means for imparting traction on the tackle.

The scoop is filled with material as it is drawn by the tackle, and as it approaches the boom, the bail gradually assumes a vertical position, in which position it is retained, to prevent tipping of the scoop when elevated, by means of the latch-bars, 29, pivoted at their forward ends to the arms of the bail, and provided with longitudinally slotted portions, as 30, free to slide on studs, 31, on the rear of the braces, 16, and 8X tending through the slots. The portions of the bars, 29, at the front ends and tops of the slots are provided with notches, 32. The said notches are so positioned that when the bail reaches its vertical position the notches will receive the studs, 31, and prevent either forward or rearward movement of the bail without the rear ends of the bars being first lifted to disengage the notched portions from the studs.

As traction on the tackle is continued, the top of the bail engages the bracket, 21, and the boom and scoop are lifted to the positions shown in dotted lines in Fig. 1.

Between the upper end portions of the frame uprights extends a shaft, 33, on which is pivoted an elongated arm, 34, held normallyrearwardly inclined out of the path of the boom, as by a counterweight arm, 35, formed integrally therewith. From its pivotal point the arm, 34:, carries a relatively shorter arm, 36, normally rearwardly extended and so disposed as to be engaged by the under side of the web of the arch, 20, as the latter moves forwardly. When thus engaged, the arm, 36, is forced downwardly and forwardly, thereby forcing the arm, 34, downwardly. The latter arm is provided at its end with a hook, 37, which engages under the cross member, 15, of the scoop, then as the tackle is slackened the arm, 84, supports the rear end of the scoop and the forward end thereof gravitates to dump the material from the scoop into the wagon.

It will be noted'that the boom moves forwardly a distance past its pivot axes until further movement is prevented by engagement of the counterweight arm with the frame member, 7

The boom is lowered by swinging it rearwardly, during which movement the web of the boom engages the under, or front side of the arm, 34, forcing the latter rearwardly until the hook is disengaged from the scoop, whereupon the counterweight restores the arms to normal position and the boom and scoop drop. The scoop may then be drawn rearwardly, the bars, 16, released as previously stated, and the operation repeated. Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is,

1. A loading machine comprising 'a suitable frame, a scoop adapted to bedrawn toward the frame and thereby filled with ma terial, mechanism for drawing the scoop toward the frame, a boom operable to elevat-e the scoop as the latter is drawn toward the frame, and means on the frame adapted to engage and support the scoop in its elevated position.
